CARBURETER FOR EXPLOSIVEENGINES. 'i

SPEGLLFICATION forming part of Letters Patent No. 694,1 10, dated February 25, 1902.

Application iiled October Z, 1900. Serial No. 31,805. (No model.)

T0 all whom t may' concern.-

Be it known that I, LOUIS H. M. SANSON, a citizen of the Republic of France, residing in Dieppe, France, have invented certain new and useful Improvements in Carbureters, of which the following is a full, clear, and exact description.

This invention has for its object a carbureter applicable to any motors for petroleum,

spirit, and the like, which carbureter differs from others of its kind in that the carbureting is produced regularly and equally.

In order to allow of the arrangement being better understood, I have shown it in the accompanying drawings, in which- Figure 1 is a vertical section, Fig. 2 a plan View, and Fig. 3 a front view, of the ring regulating the admission of air and the slide of said ring.

The aspiration is as follows: A suction-pipe is provided at a, which connects with the suc- This pipe is connected with a circular suction-chamber b, placed above the carbureting-chamber d and connected to it by a number of apertures or ports c, bored circularlyand number of rows calculated according to the' power required, the combined area of which holes exceeds slightly that of the suction-pipe o. in order to facilitate the passage of the carbureted air.

The carburetmg-ln the carbureting-chamber d a cylindrical casing e is placed, having a central upwardly-extending portion which has a domed top f. The exterior diameter of said central portion is less than the interior diameter ofthe carbureting-chamber to leave an intermediate passage e4. The casing has also an upwardly-extending portion e3 surrounding the carbureting-chamber and being of greater interior diameter than the exterior diameter of the carbureting-chamber.

to form an intermediate chamber g for fresh air. The jet of spirit comes in through a nozzle at h and is regulated by a needle-valve c', operated by a handle j.

Fresh ain-The circular fresh-air chamber g communicates with the outer air by small ports or apertures k and the number, size, and number of rows of which vary, according to the power. Their combined area slightly exceeds that of the suction-pipe. The admission of air is regulated by means of a ring Z,

Figs. l and 3, moving circularly to right or left in a helicoidal manner around the external casing of the fresh-air chamber g. This lmovement is produced by a slot m, formed obliquely in the ring and guided by a screw- -head fn., fixed in the carbureter, thus covering or uncovering the air-apertures lc. The ring is operated by a handle which may be placed at some convenient point on the motor.

Spirit-The spirit reaches the jet of the needle-valve h by a'space left free around its point t', which is in communication with a pipe o, to which is connected another pipe 1o, coming from a reservoir the iiuid in which is kept at a constant level. At q a ball-valve is provided which rests on its seat r and which has for its object to maintain in a state of equilibrium the spirit contained in the pipes p and o and around the point of the needlevalve t'.

The constant level of the luidin the reservoir is obtained by means of afloat S,which in rising turns a lever t, which pushes a valve u onto its seat. The floatl is guided in its movement by a rod e, above which is placed a cap which may be unscrewed when it is desired to see if the float is working normally. This constant-level reservoir a.' is Iixed to the carbureter proper by means of a stirrup b, Figs. 1 and 2.

' Heeten-The' cylinder e is recessed to allow of the entry of a tube c, conveying a portion of the burned gases under pressure,which escape by a hole d', formed in the cover e' of the bottom of the cylinder e, after having heated the cylinder e and its conef. e is a rod on which the ioat is mounted.

Working-The aspiration taking place at d, a vacuum is produced in the circular suction and carbureting chambers b and d through the connecting-ports c. This is the moment when the feed of spirit takes place into the carbureting-chamber CZ by the jet h of the needle-valve and of air through the fresh-air chamber g, which is connected with the outer air by ports 70. on the convex cone f of the heating-cylinder trickles in fine drops down the walls of the cylinder e, on which the current of [fresh air breaks up and becomes charged with hydrocarbon arising from the oil brought to the point of volatilization by the high tempera The spirit falling IOS) ture of the heater. The air thus oarbureted passes through the ports c into the suctionehamber, which finish the carbureting by breaking up the air, and it is then carried away by the pipe a. The carbureting oon tinues during the Whole time of aspiration. The aspiration being terminated, the spirit cannot return to the reservoir because of the opposition of the float or bali Valve q. It therefore remains in the pipe p around the point 1l of the needle-valve and is ready for commencing another cycle of operations With the next aspiration.

The aspiration is regulated by a handle y, which communicates with a tap ,e on the eentrai communication.

I claim as my invention- 1 In a oarbureter, the combination with a carburetingehamber having outlet-ports for earbureted air in its top and being open at its bottom, of a casing constructed With an upwardly-extending portion arranged Within the earburetingehamber, the exterior diam eter of which upwardly-extending portion is less than the interior diameter of the oarbureting-chamber to form an intermediate space, said casing having also a portion surrounding the oarbureting-ehamber provided with air-inlet openings, the interior diameter of which latter portion is greater than the exterior diameter of the carbureting-ehamber to form an intermediate space, means for admitting oil to the earbureting-ohamber and means for heating the upwardly-extending portion of the casing which is Within the carbureting-ohamber.

In testimony that I claim the foregoing I have hereunto set my hand this 27th day of August, 1900.
